I can't figure this one out. I think the issue is that various methods are defined under device "EC0" (note 3 chars) but when ACPI-CA attempts to call _REG, some internal function expands the name to "EC0_" (note 4 chars), which doesn't exist.

Ideas?

Thanks,
Nate

This is the source of the problems. When acpi0 fails to attach, everything else is done through the legacy PCI code. The question is, why is it failing? The above-mentioned EC method could indicate the problem is in walking the namespace but we'll have to look at the ASL to be sure.

Also, build with options ACPI_DEBUG and set these in your loader.conf:
debug.acpi.layer="ACPI_ALL_COMPONENTS"
debug.acpi.level="ACPI_LV_OPREGION"

There's a new dmesg with this done at:
